A. Delphi Examples

Program Description Keywords
A-1
ListSort.ZIP
ListSort. Use THeaderControl to define columns at design time. Change size of TStringGrid columns to match THeaderControl as part of FormCreate. Use OnSectionClick to sort column by Last Name, First Name, or ID number by using List.Sort routines.

A-2
MemoSaveDisplay.ZIP
Memo Save/Restore Display/Print. Assigning TMemo.Text to a TStringList to use SaveToFile/LoadFromFile works but trashes the ability to re-wrap text -- this save/restore operation freezes original wrapping of text in TMemo. MemoSaveDisplay first shows how to save and restore the TMemo.Text to a file using a TMemoryStream so the text is not wrapped only to fit the original TMemo. Select the Display or Print buttons to fit the contents of a TMemo manually on a canvas, either on the screen or a printer. This demo was developed to complement Hardcopy above in printing text from a TMemo box, but could also be used as a starting point for a print preview capability.

The text is parsed using a Tokens class, which is based on a finite state machine that recognizes single or multi-word tokens.

Delphi 3 Source and EXE. Order to press buttons: Read, Display, Print.

TMemo, TMemoryStream, TBitmap, Tokens, finite state machine

PageService.ZIP
Pager utility. The EXEs described below require the XPAGER32.DLL for operation, which is included in the ZIP file.  Delphi 3 Source and EXE. See ReadMe.Txt file.

Since I developed this program, a newer version of XPAGER is now available and is called Power Page. Contact Ron Tanner at www.inventiveweb.com/prod01.htm for information on how to obtain the XPDELPHI.PAS unit to recompile the Delphi projects. All my source code is in the ZIP. (Only XPAGER32.DLL can be distributed due to the license agreement.)

XPagerText.EXE. Freeware.
Quick overview of XPAGER32's capabilities.

PageService.EXE. Freeware for non-commercial use. Fee for for commercial use.
Send pages manually or via automation.

Define pager IDs and groups of pagers. Send page to list of pagers or groups.

Supports multiple paging companies. Each pager Nickname is associated with a paging company.

"Autopage" searches specified directories for specified files that become pages. Designed to work with Pinger (above) or VisualChron (below) utilities. For example, periodically ping IP addresses and page if network connection is down. Send page from any computer or device that can be configured to write simple ASCII file.

B. Utilities and Other Programs

Program Description Keywords
B-1
SysMap.ZIP
System Map. Includes BIOS, DOS, Memory and Disk Information. The Memory Map  was part of SysMap and was published as a utility, MemMap, in PC Magazine in 1990.
Turbo Pascal 7 Source and EXE.
DOS Interrupts, BIOS Interrupts
B-2
BootChk.ZIP
Boot Sector Check. Utility for scanning boot sector of a disk, and optionally, verifying CRC of boot sector. Intended to detect boot sector viruses.  Turbo Pascal 7 and assembly source, and EXE. DOS Interrupts, BIOS Interrupts, Absolute disk sector read
B-3
CharCnt
and Xlate
CharLate.ZIP
Character Count and Translate utilities. CharCnt forms a frequency distribution of characters in file, and optionally creates a translate table in a file for use with the Xlate program. Suspect some strange ASCII character in a text file? Verify this with CharCnt.

Xlate copies a file while translating characters from a table. ASCII-to-EBCDIC and EBCDIC-to-ASCII conversion tables are included for Xlate.  Turbo Pascal 7 Source and EXE.

EBCDIC.PAS  TP/Delphi EBCDIC-to-ASCII unit.

Character translation,
ASCII,
EBCDIC
CharCount Windows program to see frequency count of all bytes in file.   Updated (2013-05-08):
Download CharCount.ZIP.
Includes Delphi XE3 source code.
Added drag and drop of filename from Windows Explorer.
B-4
Gen.ZIP
Generate Text. Need a large file to measure transfer times? GenText.C (Borland 5.02 C++) or GenData.PAS (TP 7) creates files as large as you want. Each program outputs a specified number of 64-byte lines with a line number in the center and shifting text.

GenText was modified to allow up 99,999,999 records, which means it can be used to create a file of about 5.9 GB (C is a pain since the "minimum width" field automatically expanded and then precise file sizes were not maintained.). GenData allows any value as a parameter but only creates 999,999 unique records before repeating.
I/O timing tests
B-5
Music.ZIP
Music. The MusicNot.PAS unit lists the frequency of music notes (from the Handbook of Chemistry and Physics). The Music.PAS program shows the each word as a tone is played. Includes a few songs appropriate for kids, including (Frere Jacques) Are You Sleeping, Twinkle, Twinkle, Little Star, American the Beautiful, The "Alphabet" Song, Santa Claus Is Comin' to Town. This old DOS program still works in Windows 95.
